Question

Assertion (A) : Ethyl chloride gives ethyl alcohol when treated with Ag${}_2$O in boiling water.
Reason (R) : On boiling, vapour presure of water increases.

• A. Both A and R are true and R is the correct explanation to A
• B. Both A and R are true and R is not the correct explanation to A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

Answer: (B)

Both A and R are true and R is not the correct explanation to A

Ethyl chloride gives ethyl alcohol when treated with $A{g}_{2}O$ in boiling water.

Reaction of process:
$C_2{H}_{5}Cl\stackrel{aq.A{g}_{2}O}{\to }{C}_2{H}_{5}OH$

Also as we boil water, more and more water converts into vapour and due to this vapour, vapour pressure of water increases.

Option B is correct.
